Forced seed
by JonasPfi
Forced seed is a Forge world generation mod that makes newly created worlds use a seed set in its config file.
What it does
When a new world is created, the mod replaces the random seed with a predefined value from its configuration, so every new world starts from the same seed. The seed is set through the mod's config file, and a default seed is provided if none is chosen. The override applies to both singleplayer and multiplayer worlds.
The mod is a lightweight Forge mod with a single job. It is required on the server, while clients may leave it out, and it is listed as compatible with both server and client setups. Forced seed is published for Forge only, for 1.20.1, with version 1.1.1 as the latest file. The code is open source under the MIT License.
Key features
Automatic seed override
New worlds receive the configured seed without any command or manual step during world creation.
Config-based seed choice
The seed is set in the mod's config file, so server owners can pick the value that new worlds should use.
Default seed
A built-in default seed applies when no custom value has been written to the config file.
Singleplayer and multiplayer
The override works in both singleplayer and multiplayer, so the same fixed seed can be used across play styles.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Shared server worlds
Server owners who want every new world on a server to begin from the same seed can set it once in the config file.
Repeatable test worlds
A fixed seed gives the same terrain each time a new world is made, which helps when comparing builds or reproducing a layout.
Who it’s for: Server owners and players who want new worlds to start from a seed they choose rather than a random one. Because the mod runs on the server, it is most useful for administrators who control world creation.
How it compares
Seeds is a Forge mod for 1.16.5 – 1.19.2 that runs on client and server, and it is released under the MIT License without being open source. Dirt Loot is a Forge mod for 1.20.1 that needs both the client and the server, and it is under All rights reserved. Forced seed differs in that the server alone is required and the client may skip it, and it is open source for 1.20.1 only.
